Hi Team, Greetings for the day..!! We started using radclient tool for simulating radius traffic. We need your support in resolving our queries. Query 1: We are trying to send request with id as 31 using id '-i' argument in radclient command. Command used: radclient -c 1 -i 31 -n 1 -p 1 -r 1 -t 1 -sx 192.167.3.31:4444 auth testing123 -f input -d /usr/share/freeradius Output of command: Sent Access-Request Id 124 from 192.167.3.6:2001 to 192.167.3.31:4444 length 89 (0) No reply from server for ID 124 socket 3 Packet summary: Accepted : 0 Rejected : 0 Lost : 1 Passed filter : 0 Failed filter : 0 Issue is though we are specifying id number from command line, it is not considering the id and it picks some random number and sends the request. We need to simulate the id of the request. please help us out in resolving this issue Issue 2: We are trying to simulate both A & B traffic and C is the router for both MME and HSS. [image: image.png] We were able to simulate traffic from A to C(A1) and C is forwarding the request to B(A2). Now B has to send response to C(A3). Can you support us in simulating response from C. Please note that response should be sent with the corresponding request id only. Free radius version used: 3.0.13 Utils version used: freeradius-utils-3.0.13-15.el7.x86_64 Attached is the radiusd output. -- ------------------------ Regards Tejeswi K +91-8880007462 -----------------------
